There was no F/book cookie, as I have quite clearly said.
I ALWAYS CLEAR COOKIES before and after going to f/book.
I'm talking about your
Yahoo cookies. Did you clear those too?
Anyway, it doesn't have to be the cookie file. I'm no webmaster, but there are probably other avenues by which a website can determine the email identities of its visitors.
At least such would come as no surprise to me.
